Common reducer types

(A) Helical Worm Geared Motors harmonic transmission is the use of flexible components to control the elastic deformation to transfer movement and power, the volume is not large, high precision, but the disadvantage is the limited life of the flexible wheel, impatience impact, rigidity and metal Pieces are relatively poor. The input speed can not be too high.
(B) planetary reducer has the advantage of relatively compact structure, small return gap, high precision, long life, rated output torque can be done very large. But the price is slightly expensive
(C) cycloidal speed reducers is characterized by a reverse self-locking function, you can have a larger reduction ratio, the input shaft and output shaft is not on the same axis, nor in the same plane. But the general volume is larger, the transmission efficiency is not high, the accuracy is not high.

Reducer type

General gear reducer with helical gear reducer including parallel shaft helical gear reducer, Helical Bevel Geared Motors, bevel gear reducer, etc., planetary gear reducer, cycloid reducer, worm gear reducer, planetary friction machine Class gear and so on.
The cycloidal speed reducer is generally used for low-speed and high-torque transmission equipment, the motor. Internal combustion engine or other high-speed operation of the power through the reducer on the input shaft teeth less gear meshing the output gear on the gear to achieve the purpose of deceleration, Reducer will have several pairs of the same principle gear to achieve the desired deceleration effect, the size of the gear ratio of teeth, is the transmission ratio.

The role of reducer

(1) speed at the same time cycloid reducers the load inertia, inertia reduced to the square of the reduction ratio. We can look at the general motor has a value of inertia.
(2) Deceleration simultaneously increase the output torque, torque output ratio by motor output multiplier, but be careful not to exceed the cycloidal speed reducer rated torque.

Why the planetary gearing opportunities appear broken shaft imagination.

The first possible problem with the broken shaft is the quality of the coal mill gearbox. Of course, this is what we usually think of people, one of the most important reason is the usual use of the process of the reasons. For example, in the use of planetary reducer acceleration and deceleration in the process of how we should pay attention to what a good way. The following is a summary of the three reasons for the Shanghai.
First, some applications must strictly abide by this criterion, which is not only the protection of the reducer, more important is to avoid the planetary reducer output shaft was broken. This is mainly because, if the equipment is installed, the output shaft of the helical geared motors unit and its load are stuck, and then the overload capacity of the drive motor will continue to increase its output, which may cause the output shaft of the gear unit Of the force exceeds the rated output torque of the output shaft.
Second, in the process of acceleration and deceleration, the planetary reducer output shaft by instantaneous torque if more than its rated output torque of 2 times, and this acceleration and deceleration and too frequent, then the final will make the gear off axis. Taking into account the emergence of this situation less, so here is no further introduction.
Third, the wrong selection of the reducer caused by the output is not enough. Some users in the selection, mistakenly believe that as long as the selected planetary reducer rated output torque to meet the work requirements can be, it is not true, one is equipped with the rated output torque multiplied by the reduction ratio, the value is in principle to be less than The sample output of the similar speed reducer rated output torque, and second, but also to consider the drive motor overload capacity and the actual required maximum working torque. In theory, the user needs the maximum working torque. Must be less than 2 times the rated output torque of the reducer.
Which must use the planetary reducer must pay attention to its code of conduct, while the wrong selection of fatal reason is not enough reason. Reducer output is too small to break the axis of the problem, planetary reducer broken axis is a common problem. In addition to the reducer output end of the concentricity is not good, resulting in the reducer off the shaft.
